Japan's SBI Group Is Building Asia's First Cross-Border Digital Asset Empire

Japan's SBI Group is consolidating exchanges, stablecoins, and tokenization infrastructure across Asia in a bid to control the entire digital asset value chain from issuance through settlement and retail distribution. The strategy, announced in July 2026, represents the first attempt by an Asian financial institution to build what executives describe as a unified regional corridor for digital assets.

SBI, Japan's largest online securities firm with more than 14 million users and $308 billion in assets under custody, acquired a majority stake in Singapore-based crypto platform Coinhako, which holds a Major Payment Institution license from the Monetary Authority of Singapore (MAS). The move pairs SBI's capital and regulatory relationships with Coinhako's regional presence and MAS approval, per CoinDesk reporting. SBI CEO Yoshitaka Kitao stated, according to CoinDesk: "The SBI Group seeks to establish a global corridor for digital assets by connecting exchanges worldwide."

The group is simultaneously building settlement infrastructure with Ondo Finance to tokenize Japanese equities and other assets using its JPYSC stablecoin, a yen-backed digital currency. Additionally, the Solana Foundation will take an equity stake in SBI R3 Japan, to be renamed SBI Solana Global, focusing on issuing stablecoins and tokenizing real-world assets such as corporate bonds and real estate. These moves complement SBI's June 2026 agreement to acquire Tokyo-based exchange Bitbank for approximately $289 million, with closing expected in October subject to regulatory approval. SBI previously acquired crypto exchange Bitpoint in 2022.

Joseph Goh, director and head of Asia Pacific at Areta, told CoinDesk that SBI is the first financial group in Asia attempting to control the entire digital asset value chain at once, "from issuance and settlement through trading infrastructure, asset management and retail distribution, and to do it across the region rather than only at home." Goh characterized yen-based on-chain settlement as "the real prize" and "one of the most strategic positions in Asian finance over the coming decade."

However, significant constraints limit the infrastructure's current utility. According to SBI, JPYSC is currently limited to accounts within SBI VC Trade and does not yet support withdrawals to external wallets or remittances and settlements via public blockchains. This restriction severely limits interoperability outside SBI's proprietary system. Sota Watanabe, CEO of Startale Group, which works with SBI Holdings on JPYSC, stated per CoinDesk: "SBI Holdings' continued commitment to digital assets likely signals confidence in the future architecture of global finance," adding that blockchain is increasingly viewed as financial infrastructure rather than an emerging technology.

SBI's investment strategy extends beyond Coinhako and stablecoins. The firm led a $76 million Series C funding round for institutional exchange EDX Markets and a $25 million Series C round for crypto risk manager Gauntlet, according to CoinDesk. SBI stated its investment strategy is based on long-term infrastructure development rather than short-term crypto market cycles.

Key execution risks include regulatory approval for the Bitbank acquisition, timeline and conditions for JPYSC to support external wallet withdrawals and public blockchain settlements, and the ability to navigate regulatory differences across Singapore, Japan, and other Asian markets operating the cross-border corridor. No details have been provided on the percentage stake SBI acquired in Coinhako or the specific Japanese equities and asset classes Ondo Finance will tokenize or when those products will launch.
